plug nothing into the right input (jacks 4, 6, or 8)— this
way the signal will appear on both sides. This trick is
called “jack normalling.”
4. CHANNEL INSERT (Channels 1–2)
These jacks are where you connect serial effects
such as compressors, equalizers, de-essers, or filters.
Since most people don’t have more than a few of these
gadgets, we’ve included inserts for just the first two
channels. If you want to use this kind of processing on
channels 3 through 8, simply patch your source through
your processor before you plug into the 802-VLZ3.
The channel insert points are after the gain [7] and
low cut [5] controls, but before the channel’s EQ [25-
27] and level [21] controls. The send (tip) is low-im-
pedance (120 ohms), capable of driving any line-level
device. The return (ring) is high-impedance (over 2.5 k
ohms) and can be driven by almost any device.
See Appendix B for details and drawings about Insert
cables, and a diagram showing three ways to use the
jacks.
Besides being used for inserting external devices,
these jacks can also be used as channel direct outputs;
post-gain, post-low cut, and pre EQ. In fact, Mackie
mic preamps have become so famous, that people buy
the mixers just to have some of these preamps in their
arsenal.
2. LINE INPUTS (Channels 1–2)
These inputs share circuitry (but not phantom power)
with the mic preamps, and can be driven by balanced
or unbalanced sources at almost any level. You can use
these inputs for virtually any signal you’ll come across,
from instrument levels as low as –40 dB to operating
levels of –10 dBV to +4 dBu, since there is more gain
available than on line inputs 3–8.
To connect balanced lines to these inputs, use a 1⁄4"
Tip-Ring-Sleeve (TRS) plug, the type found on stereo
headphones.
To connect unbalanced lines to these inputs, use a
1⁄4" mono (TS) phone plug or standard instrument
cable.
The line inputs 1–2 are a good place to connect older
instruments that need more gain. You can correct weak
levels by adjusting the corresponding channel’s gain
control.
3. STEREO LINE INPUTS
(Channels 3–4, 5–6, and 7–8)
These fully-balanced inputs are designed for stereo or
mono, balanced or unbalanced signals. They can be used
with just about any professional or semi-pro instrument,
effect or tape player.
In the stereo audio world, an odd-numbered chan-
nel usually receives the “left signal.” For example, you
would feed the 802-VLZ3’s line inputs 5-6 a stereo signal
by inserting the device’s left output plug into the chan-
nel 5 jack, and its right output plug into the channel 6
jack.
When connecting a mono device (just one cord),
always use the left (mono) input (jacks 3, 5, or 7) and
